Copforce Extra – double strength in protection against late blight and downy mildew

Copforce Extra is a modern fungicide with systemic and contact action, designed to protect potato, field tomato and grapevine against the most dangerous fungal and pseudo-fungal diseases. It contains two active substances: cymoxanil (60 g/kg) and copper in the form of copper hydroxide (300 g/kg). The product is available as water dispersible granules (WG), ensuring ease of use and good solubility.

Advantages of using Copforce Extra

• Rapid and intervention action
• Systemic and contact action – double protection
• Resistant to washing off, remains on leaves for a long time
• Can be used under high infection pressure conditions
• Versatility – use on potato, tomato and grapevine

Mode of action

• Cymoxanil – systemic and intervention action, inhibits infection development at early stages.
